Is there a manual for yatagans?

Manolo,
These look like janissaries. As Ariel and you suggested there might be also some confusion about dating. (These much look like the 18th and the early 19th century dresses to me)

For the first one on the left I am not sure. But the second one on the left is a serdengecti ( janissary volunteer), the third one is a karakollukcu (a janissary orderly) and the last one is a harbeci (janissary guardsman).
